Dock3
Dock3 (Dedicator of cytokinesis 3), also known as MOCA (modifier of cell adhesion) and PBP (presenilin-binding protein), is a large (~180 kDa) protein involved in intracellular signalling networks. It is a member of the DOCK-B subfamily of the DOCK family of guanine nucleotide exchange factors (GEFs) which function as activators of small G proteins. Dock3 specifically activates the small G protein Rac.
Discovery
Dock3 was originally discovered in a screen for proteins that bind presenilin (a transmembrane protein which is mutated in early onset Alzheimer's disease). Dock3 is specifically expressed in neurones (primarily in the cerebral cortex and hippocampus).
Structure and function
Dock3 is part of a large class of proteins (GEFs) which contribute to cellular signalling events by activating small G proteins. In their resting state G proteins are bound to Guanosine diphosphate (GDP) and their activation requires the dissociation of GDP and binding of guanosine triphosphate (GTP). GEFs activate G proteins by promoting this nucleotide exchange.

Virginity
by: TG4I know you want it
You wanna hit it
But you can't have it
Oops, can't touch it
Maybe a kiss on these lips
Holding hands it aint nothing
Nasty is what you call me
We get close but you can't handle it
Cuz I'm not maybe what your looking
Cuz I'm not the average kind of girl
I might let you touch me
I might let you hold me
I might even let you kiss me
But you can not take my virginity
I might let you tease me
I might let you squeeze me
I might even let you kiss me
But you can not take my virginity
Can't imagine what it feels like
My friends say it's alright
But then they go and do it all night
But I prefer the merry life
Patience is what you gotta have
That's what it takes to be my man
I'm not like that bad if you like me
Keep it with you then maybe
I might let you touch me
I might let you hold me
I might even let you kiss me
But you can not take my virginity
I might let you tease me
I might let you squeeze me
I might even let you kiss me
But you can not take my virginity
Baby its not like I dont really like you
You just gotta know
That if your not willing to get with my loving
Than you've gotta go
Baby its not like I dont really like you
You just gotta know
That if your not willing to get with my loving

Girl you gotta keep your integrity
I wouldn't let him get over on me
Dont fall for the same game
Him callin you boo
Telling you he love you
And everything he gone do
Treat your body like a temple
The best thing ever made
Cuz once you let him hit
Watch how those feelings fade away
You gotta be the best at this game being played
Dont give it up know
Some things are better off saved
I might let you touch me
I might let you hold me
I might even let you kiss me
But you can not take my virginity
I might let you tease me
I might let you squeeze me
I might even let you kiss me
